I commute 70 + miles round trip daily. About half of it on the interstate. The stuff I have seen people (mostly young women) doing while driving is unbelievable.
One that really stands out was the girl steering with her knees while applying mascara with one hand, cigarette up next to the cracked window with the other and a bowl of cereal on her lap that she would take bites of in between trying to apply her make up in the rear view mirror. The worst part was she had two little kids that looked like 2 year old twin girls in the back seat. That one got called in.
